However, a spokesperson for United explained to Fox News that the airline told the customer she couldn’t bring the peacock on board.

"This animal did not meet guidelines for a number of reasons, including its weight and size. We explained this to the customers on three separate occasions before they arrived at the airport," United said in a statement, according to Fox News.

United added in a statement that it continues to support customers with emotional support animals, NBC News reported.

“We know that some customers require an emotional support animal to assist them through their journey,” the statement said. “In order to ensure we provide the best service to everyone on board our flights, consistent with government rules we currently require these customers to provide documentation from a medical professional and at least 48 hours advance notice.”

The travel talk show The Jet Set shared photos of the incident on Facebook.
